Description

The Victron Energy 12V 165Ah AGM Deep Cycle is a sealed, maintenance-free VRLA battery built on flat plate Absorbent Glass Mat construction. The electrolyte is held in a glass-fibre mat between the plates, so the battery is spill-proof and can be mounted in any orientation. Its low internal resistance gives strong high-current performance, suiting marine loads such as inverters, bow thrusters and electric winches.

The 165Ah rating is quoted at the 20 hour rate, with 150Ah available at the faster 10 hour rate. Lead-calcium grids and high-purity active materials keep self-discharge below 2% per month, allowing extended storage between charges. As with any lead-acid battery, life is longest when discharges are kept shallow and the battery is recharged promptly with a suitable charger.

This version is fitted with M8 drilled, flat copper insert terminals for a direct, high-contact connection, making it well suited to permanently installed house and service banks on larger vessels.

Why are two capacities, 150Ah and 165Ah, quoted?
Lead-acid capacity depends on discharge rate. The 165Ah figure is the rated capacity at the 20 hour rate (C20), while 150Ah is the capacity at the faster 10 hour rate (C10).
What type of terminal does this battery use?
It is fitted with M8 drilled, flat copper insert terminals, which give a direct high-contact connection without the need for separate clamp terminals.
What charge voltages should I use?
Victron specifies an absorption voltage of 14.2 to 14.6V, a float voltage of 13.5 to 13.8V and a storage voltage of 13.2 to 13.5V for a 12V battery, with temperature compensation of -24 mV/°C.
How many charge and discharge cycles can it deliver?
The cycle design life is 400 cycles at 80% depth of discharge, 600 cycles at 50%, and 1500 cycles at 30%. Keeping discharges shallow greatly extends service life.
Does the battery need maintenance?
No. It is a sealed valve-regulated (VRLA) AGM battery and is maintenance-free for life; gas only escapes through the safety valves in the event of overcharging.
